DETAILED DESCRIPTION
[0025] Some embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments are shown. Indeed, various embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.
As discussed herein, the protection devices may be referred to use by humans, but may also be used to raise and lower objects unless otherwise noted.
[0026] The components illustrated in the figures represent components that may or may not be present in various embodiments of the invention described herein such that embodiments may include fewer or more components than those shown in the figures while not departing from the scope of the invention. Some components may be omitted from one or more figures or shown in dashed line for visibility of the underlying components.
[0027] Example embodiments of the present disclosure provide various example harness configurations to allow for, in some examples, increased reliability of front anchors during use. In some examples, front anchored harnesses need to be able to withstand dynamic and static tests, such as EN/ANSI/GB or other region standards.
Current front anchor harnesses often employ a chest webbing sewed to a single torso webbing on each end of the chest webbing. In such current harnesses, the sewed regions struggle to withstand sufficient force to pass the required testing and therefore cannot be used in operation.
[0028] Various example embodiments of the present disclosure use a multi-webbing configuration to allow for a better distributed forces during both static and dynamic operations of a harness. Specifically, example embodiments described herein divide or otherwise separate torso webbing into at least two separate webbings (e.g., upper webbing and lower webbing). In such example embodiments, the at least two separate webbings are mated or otherwise connected by way of a chest webbing (e.g., horizontal connecting webbing). Advantageously, and in some examples, when force is applied to the chest webbing by way of a force acting on a force receiving mechanism (e.g., a D-Ring) the force is concentrated, in some examples, on folds or loops in the at least two separate webbings and, in some examples, avoids or otherwise diminishes stress and/or tearing on a sewing pattern on the at least two separate webbings. Additionally, various embodiments discussed herein may allow for reduced manufacturing costs and increased ease of manufacturing.
[0029] FIGS. 1A-1C are various different views of a harness of an example embodiment as worn during operation. Specifically, FIG. 1A illustrates a front view of an example embodiment as worn during operation, FIG. 1B illustrates a side view of an example embodiment as worn during operation, and FIG 1C illustrates a real view of an example embodiment as worn during operation.
[0030] As shown in FIG. 1A, the harness 100 may have an upper harness portion 101 configured to be worn on the upper body of a user during operation and a lower harness portion 130 configured to be worn on the waist and/or below the waist of the user during operation. In various embodiments, as discussed in more detail below with reference to FIGS. 2 and 3, the upper harness portion 101 may include a first upper webbing 110, a first lower webbing 115, a second upper webbing 120, a second lower webbing 125, and a horizontal connecting webbing 105.
[0031] In various embodiments, each of the first upper webbing 110 and the first lower webbing 115 may be attached to the horizontal connecting webbing 105 at a first end 155 of the horizontal connecting webbing. In various embodiments, each of the second upper webbing 120 and the second lower webbing 125 may be attached to the horizontal connecting webbing 105 at a second end 160 of the horizontal connecting webbing 105. In various embodiments, the horizontal connecting webbing 105 may include a fastening mechanism 260 configured to allow the harness to be removed and/or equipped. In various embodiments, the horizontal connecting webbing 105 may include a force receiving mechanism 265 configured to receive a clip, rope, cable, carabiner, and/or the like. In some embodiments, the force receiving mechanism 265 may be a D-ring that is attached to the horizontal connecting webbing 105 In some embodiments, the force receiving mechanism 265 may be a webbing loop (e.g., similar to the loops discussed herein).
[0032] In various embodiments, the lower harness portion 130 may include a waist webbing 135, and one or more leg webbings 140, 145. In various embodiments, various components of the upper harness portion 101 may be attached to various components of the lower harness portion 130. For example, as shown, each of the first lower webbing 115 and the second lower webbing 125 may be attached to the waist webbing 135. In some embodiments, as shown in FIG. 1B, the first upper webbing 110 and the second upper webbing 120 may each be attached to one of the leg webbings 140, 145. In various embodiments, the first upper webbing 110 and the second upper webbing 120 may be configured to cross over one another (e.g., within a webbing crossing housing 150) along the back of a user when equipped. In some embodiments, as shown, additional force receiving mechanisms may be placed at various positions along the harness for different application (e.g., a force receiving mechanism is provided within the webbing crossing housing 150).
[0033] In various embodiments, the material of the various webbings may be based on a given application of the harness. In various embodiments, the various webbings discussed herein may be made out of polyester, nylon, and/or the like. In various embodiments, the size and shape of the webbings may be based on the weight to be carried during operation. In various embodiments, the webbing size (e.g., thickness, width), webbing material, and/or attachment methods (e.g., sewing pattern may be increased) may be chosen based on the weight to be carried during operation (e.g., a 125 kg harness may have webbing with a larger thickness than the webbing of a 100kg harness).
[0034] FIG. 2 illustrates horizontal connecting webbing connections in accordance with various embodiments of the present disclosure. In various embodiments, the horizontal connecting webbing 105 may have a first horizontal receiving loop 200 defined at the first end 155 of the horizontal connecting webbing 105 (or 105A in an instance in which the horizontal connecting webbing 105 may have a fastening mechanism 260A, 260B).

In various embodiments, the attachment of the second upper webbing 120 to itself may be achieved via sewing.
[0038] In some embodiments, the second lower webbing 125 is folded onto itself, such that the second lower webbing loop 235 is created (e.g., the loop end 255 of the second lower webbing 125 may be attached to itself at a second lower webbing attachment point 285). The second lower webbing loop 235 is passed through the second horizontal receiving loop 205, such that the second lower webbing loop 235 and the second horizontal receiving loop 205 are linked. In various embodiments, the attachment of the second lower webbing 125 to itself may be achieved via sewing.
[0039] In various embodiments, the second upper webbing 120 and the second lower webbing 125 are independent from one another, such that the second upper webbing 120 and the second lower webbing 125 are able to move relative to one another during operation.

[0048] FIG. 5A is a harness of an example embodiment experiencing dynamic force testing in an instance in which the test dummy is dropped feet-first from a predetermined height . As shown, the resultant force is in the head-first direction, which is received by the harness 100, causing the horizontal connecting webbing 105 to move in the head-first direction, which applies a substantial portion of the force on the first lower webbing 115 and the second lower webbing 125 (e.g., at the loops 225, 235 of the first lower webbing 115 and the second lower webbing 125). Alternatively, as shown in FIG. 5B, in an instance the harness 100 experiences dynamic force testing in an instance in which the test dummy is dropped head-first from a predetermined height). As shown, the resultant force is in the feet-first direction, which is received by the harness 100, causing the horizontal connecting webbing 105 to move in the feet-first direction, which applies a substantial portion of the force on the first upper webbing 110 and the second upper webbing 120 (e.g., at the loops 220, 230 of the first upper webbing 110 and the second upper webbing 120).
[0049] FIG. 6A is a harness of an example embodiment experiencing a horizontal static force test with the test dummy being hung in the feet-first direction In various embodiments, the operations are similar to the dynamic force shown in FIG. 5A.
For example, the resultant force is in the head-first direction, which is received by the harness 100, causing the horizontal connecting webbing 105 to move in the generally head-first direction (e.g., direction is opposite of gravity). As such, the substantial portion of the force is focused on first lower webbing 115 and the second lower webbing 125 (e.g., at the loops 225, 235 of the first lower webbing 115 and the second lower webbing 125).
Alternatively, as shown in FIG. 6B, in an instance in which a static force test is applied with the test dummy being hung in the head-first direction. As shown, the resultant force is in the feet-first direction, which is received by the harness 100, causing the horizontal connecting webbing 105 to move in the generally feet-first direction (e.g., along with gravity). As such, the substantial portion of the force is focused on the first upper webbing 110 and the second upper webbing 120 (e.g., at the loops 220, 230 of the first upper webbing 110 and the second upper webbing 120).
[0050] FIGS. 7A and 7B are additional testing situations for a harness of an example embodiment. FIG. 7A illustrates a vertical static test in an instance in which the dummy is hung in the feet-first with similar results to FIG. 6A. As shown, the resultant force is in the head-first direction, which is received by the harness 100, causing the horizontal connecting webbing 105 to move in the generally head-first direction (e.g., direction is opposite of gravity). As such, the substantial portion of the force is focused on first lower webbing 115 and the second lower webbing 125 (e.g., at the loops 225, 235 of the first lower webbing 115 and the second lower webbing 125). Additionally, FIG. 7B
illustrates a vertical static test in an instance in which the dummy is hung in the head-first directional force with similar results to FIG. 6B. As shown, the resultant force is in the feet-first direction, which is received by the harness 100, causing the horizontal connecting webbing 105 to move in the generally feet-first direction (e.g., along with gravity). As such, the substantial portion of the force is focused on the first upper webbing 110 and the second upper webbing 120 (e.g., at the loops 220, 230 of the first upper webbing 110 and the second upper webbing 120).
[0051] The present disclosure provides various example harness configurations to allow for increased reliability of front anchors during use. Front anchored harnesses need to be able to withstand dynamic and static tests, such as EN/ANSI/GB or other region standards. Current front anchor harnesses struggle to pass such tests and therefore cannot be used in operation. Various embodiments of the present disclosure use a multi-webbing configuration to allow for a better distributed forces during both static and dynamic operations of a harness.
[0052] Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Moreover, although the foregoing descriptions and the associated drawings describe example embodiments in the context of certain example combinations of elements and/or functions, it should be appreciated that different combinations of elements and/or functions may be provided by alternative embodiments without departing from the scope of the appended claims. In this regard, for example, different combinations of elements and/or functions than those explicitly described above are also contemplated as may be set forth in some of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
